These downpipes for the N55 engine in the 2013-2016 F22 M235i, F30 335i, and F32 435i improve power, torque, turbo efficiency, and make the engine louder. All advantages that your F22/F30/F32 track car will benefit from. The Wagner Tuning M235i/335i/435i downpipes flow better than stock and other designs thanks to CAD engineering, oversized stainless steel piping, and OE-style connectors. These are some of the best fitting N55 downpipes we have seen to date. The Wagner DP increases power by eliminating restrictions in the stock pipes. Reducing backpressure makes the turbo more efficient and longer-lasting while minimizing the potential for fault codes and limp modes when on track. With less backpressure the turbo can spool up faster and be more responsive - more boost is available sooner and with less lag.
Fitment note: Only for cars with a production date of 7/2013 (July 2013) or newer. Not for cars built before 7/13. If your car is a 2014, 2015 or 2016 model year you should not need to check your production date, but if you have a 2013 you will need to check it. The production date can be found on the driver's side door jamb VIN plate.
This is a racing downpipe intended for track and race cars that no longer go through emissions testing and is sold for off-road and/or competition use only.
